Modelling of sediment supply from torrent catchments in the Western Alps using the sediment contributing area (SCA) approach

چکیده

The production of coarse sediment in mountain landscapes depends mainly on the type and activity geomorphic processes topographic natural conditions (e.g. vegetation cover) these catchments. supply from slopes to streams its subsequent transport lead connectivity, which describes integrated coupled state systems. Studies Northern Calcareous Alps show that size contributing area (SCA), a subset drainage effectively delivers channel network, can be used as predictor delivery streams. SCA concept is delineated digital elevation model (DEM) using set rules related steepness length directly adjacent gradient latter cover. present study investigates applicability this Western identify geomorphologically active areas estimate mean annual yield (SY) debris-flow-prone We use statistical approach shows parameter optimisation linear regression SY extent. dataset ~25 years assessed accumulation 35 retention basins. In investigated catchments, governed by several factors, extent vegetation-free with minimum slope 23° network very low latter. With our improved framework, we applied catchments are widely distributed, large spatial scale (hectare area) heterogeneous their properties. general, high resulting significant correlations between long-term average SCA.

Sediment patches, sediment supply, and channel morphology

Bed surface particle size patchiness may play a central role in bedload and morphologic response to changes in sediment supply in gravel-bed rivers. Here we test a 1-D model (from Parker ebook) of bedload transport, surface grain size, and channel profile with two previously published flume studies that documented bed surface response, and specifically patch development, to reduced sediment sup...
